The Effects of Formic Acid or Formic Acid Plus Molasses Additives on the Fermentation Quality and Dm and Adf Degradabilities of Grass Silage
(Tubitak Scientific & Technological Research Council Turkey, 2003) Baytok, E; Muruz, H
This experiment was carried out to evaluate the effects of formic acid and formic acid plus molasses additives on the grass silage fermentation characteristics and degradability of dry matter (CM) and acid-detergent fibre (ADF). Grasses were cut in early (experiment I), middle (experiment II) and late maturity (experiment III). The additive treatments in experiments I, II and III were: 1) Untreated; 2) 0.5% Formic acid (FA): 3) FA+2% molasses: 4) FA+4% molasses; and 5) FA+6% molasses. The silages were ensiled in jar silos (1 L) and DM and ADF degradability were determined by using the nylon bag technique in the rumens of four fistulated sheep. Increasing formic acid plus molasses decreased the ADF and neutral detergent fibre (NDF) content of silages as compared with FA and untreated silages in experiments I, II and III (p < 0.001). Formic acid plus molasses silages were well 1 reserved with low pH (4.62, 4.51, 4.54), high lactic (30.62, 32.20, 28.54 g kg(-1) DM) and acetic acid (19.21, 21.46, 20.65 g (kg-1) DM) and low butyric acid (3.81, 2.19, 1.43 g (kg-1) DIM) as compared with untreated silages (pH: 5.12, 5.35, 5.36; lactic acid: 20.70, 21.47, 15.21 g (kg-1) DIM; acetic acid: 14.32, 15.88, 11.28 g (kg-1) DIM; butyric acid: 4.50, 3.47, 6.68 g (kg-1) DIM in experiments I, II and III, respectively). However, silage fermentation quality was not at the optimal level. The FA silages were moderately preserved with more restricted fermentation than the formic acid plus molasses and untreated groups. In experiments I, II and III, significant differences were noticed between untreated and other silages in respect of DM degradability. ADF degradability was not affected by the silage treatments at 4, 16 and 24 h, but was significantly (p < 0.01 or p < 0.001) affected at other times.
Effects of Formic Acid, Molasses and Inoculant Additives on Corn Silage Composition, Organic Matter Digestibility and Microbial Protein Synthesis in Sheep
(Elsevier, 2006) Aksu, T; Baytok, E; Karsli, MA; Muruz, H
This study examined the production of com silages with low or high lactic acid concentrations, provided by the addition of formic acid (0.5%), molasses (5%) or microbial inoculant (homofermentative lactic acid bacteria, 10 g/tonne). After the fermentation period, sheep were fed the silages to determine true and apparent digestibility of the organic matter and microbial protein synthesis. The experiment were carried out with four KivircikxMorkaraman sheep, 1.5 years old, fixed with cannula in their rumen and duodenum. Lactic acid concentrations were significantly higher in silages treated with enzyme or molasses compared to other specific treatments. Acetic acid concentration was highest in silage treated with formic acid, and lowest in silage treated with molasses (P < 0.05). The by-pass of crude protein was highest in silage treated with formic acid. (c) 2005 Elsevier B.V. All rights reserved.
The Effects of Formic Acid, Molasses and Inoculant as Silage Additives on Corn Silage Composition and Ruminal Fermentation Characteristics in Sheep
(Tubitak Scientific & Technological Research Council Turkey, 2005) Baytok, E; Aksu, T; Karsli, MA; Muruz, H
The objective of this study was to determine the effects of formic acid, molasses, and microbial inoculant (homofermentative lactic acid bacteria) as silage additives on silage quality and ruminal fermentation characteristics. Silages with or without formic acid (0.5%), molasses (5%), or microbial inoculant (10 g/t) were fed to ruminally cannulated, 1.5 year-old Kivircik x Morkaraman sheep. Silage treated with molasses had significantly greater DM and CP concentrations compared with other groups (P < 0.05). pH values did not significantly differ among treatments (P > 0.05). Lactic acid concentrations were significantly higher in silages treated with enzyme or molasses compared with others (P < 0.05). While acetic acid concentration was the highest in silage treated with acid, it was the lowest in silage treated with molasses (P < 0.05). Silage NH3-N concentration was the highest in silage treated with molasses, but the lowest in silage treated with acid (P < 0.05). Post-feeding ruminal total organic acid concentrations were significantly greater in sheep fed silages with additive than the control (P < 0.05). While percentages of acetic acid were greater, percentages of butyric acids were less in the rumen fluid of sheep fed silage without additive compared with the rumen fluid of sheep fed silage treated with silage additives. However, percentages of propionic acid did not differ among treatments.
